I use this to assist in water changes for aquariums. This adapter will prevent blowing your substrate/corals/plants around. Printed with supports on the build plate. If you print in PETG and pull the adapter straight from the build plate the supports will rip clean off :)

I modified this a bit to fit snugly around 1" o.d hose. You will need to use warm water to loosen the hose to slide over the fitting. I also lengthened the bit that the hose attaches to.
